Detailed Description
Failpoints allow for injecting fake errors into running code on the fly, without modifying code or recompiling with flags. Failpoints are always present, and are very efficient when disabled. Failpoints are described in man fail(9).

| ) |
Initialize a fail_point. The name is formed in a printf-like fashion from "fmt" and subsequent arguments. This function is generally used for custom failpoints located at odd places in the sysctl tree, and is not explicitly needed for standard in-line-declared failpoints.
